QingQi (Qlink) 200GY Illustrated Valve Adjustment

[Real4real]

The sales department sent the english version of the specs reqested, the request was sent to the enginering department who wrote these specs to sales in Chinese. I have this all in my inbox but didn't feel the need to share this and edit the email addresses to post the requested information here.
I'll give you and E for effort to prove your point.
By the way, the clearences given are the clearences requiered for oil to lubricate the cams, rockers and valves. By setting your exaust clearences loose you are in fact changing the duration of the exaust valve, causing it to close sooner and in some cases increasing the power of the engine. This is incorrect and very poor mechanical practice to gain a half a horse. Some engines allow you to dial in the cams to achieve changing the duration without causing damage to the valve train. Also your rocker to valve clearences increase in modern Chinese engines when the engine gets hot due to the geometry of rocker pivot to valve contact hight together with the thermal growth of the rocker itself.
Please stop posting poor information, there are people visiting this forum for information to maintain thier engines and the info your posting and trying to prove could cause damage to an engine. The clearences your posting to use are old school enginering.
My 2009 China bike uses a Suzuki based engine still in production except for the rocker system, this has been updated with better materials and re-enginered to reduce excessive clearences reducing noise and increasing the max RPM and power output. The Suzuki engine has been in production for a while and the Japanese haven't bothered to update this design because the engine is selling as an entry level power sorce and re-tooling for a couple of horse power isn't economical. Yes I am saying the Chinese engine in my bike is better in some ways than the Suzuki engine it's some what based on.
I have never done sales myself, in fact I am a profesional maker. I have done it all, CAD design of parts and assemblies, pattern making for casting production, machining the parts for assembly and assembly the mechanical finalization of the making process. I have done this for small engine, automotive and large engines with pistons that required a crain to be lifted and many other applications. That's how I know my stuff. Nice try again.
You are obviously an amature mechanic who thinks too much of yourself MJH. I have been clear and reasonable with my experience and defined my reasons for giving the advice I've given. The only thing I have seen from you MJH is insults to the manufacturers of the bikes I thought we all enjoy. Try to dig up some facts or proof of the accusations and poor mechanical practices you so easily pass around.
